chore: Port FreeSewing.dev to docusaurus

The replaces the NextJS site powering FreeSewing.dev with a Docusaurus
setup. It's part of my efforts to simplify FreeSewing's setup so we can
focus on our core value proposition.

+title: Path.divide()
+---
+
+The `Path.divide()` method breaks a path apart in an array of atomic paths. An
+atomic path is a path that can't be divided further and is always made up of
+one move + one drawing operation.
+
+## Signature
+
+```js
+array path.divide()
+```
+
+## Example
+
+<Example caption="Example of the Path.divide() method">
+```js
+({ Point, points, Path, paths, part }) => {
+
+  points.A = new Point(55, 40)
+  points.B = new Point(10, 70)
+  points.BCp2 = new Point(40, 20)
+  points.C = new Point(90, 60)
+  points.CCp1 = new Point(50, -30)
+  points.D = new Point(50, 80)
+  points.DCp1 = new Point(140, 50)
+
+  paths.example = new Path()
+    .move(points.A)
+    .line(points.B)
+    .curve(points.BCp2, points.CCp1, points.C)
+    .curve(points.DCp1, points.DCp1, points.D)
+    .close()
+
+  let style = "stroke-width: 4; stroke-opacity: 0.5;"
+  let i = 0
+  for (let p of paths.example.divide()) {
+    i++
+    paths[i] = p
+      .attr("style", style)
+      .attr('style', `stroke: hsl(${i * 70}, 100%, 50%)`)
+  }
+
+  return part
